Functions

Public

Name Remarks Include Path Unreal Specifiers

bool AreAllBelowThreshold ( const int32 Index0,
const int32 Index1,
const int32 Index2,
const float Threshold
) const

bool AreAnyBelowThreshold ( const int32 Index0,
const int32 Index1,
const int32 Index2,
const float Threshold
) const

 Return whether at least one of the specified triangle points has weight below (or equal) to the specified PointWeightMap.h  

void CalcRanges ( float& MinValue,
float& MaxValue
)

 Calculates Min/Max values based on values. PointWeightMap.h  

void Empty()

 Empty this map of any values. PointWeightMap.h  

float GetValue ( int32 Index
) const

 Get a value from the map, or return 0 if the index is out of bounds. PointWeightMap.h  

void Initialize ( const FPointWeightMap& Source,
T Target
)

 Initialize a weight map from another weight map while enabling and setting a new target. PointWeightMap.h  

void Initialize ( const int32 NumPoints
)

 Reset this map to the specified number of points, and set all the values to zero. PointWeightMap.h  

bool IsBelowThreshold ( const int32 Index,
const float Threshold
) const

 Return whether the specified point weight is below (or equal) to the specified threshold. PointWeightMap.h  

bool IsZeroed()

 Return whether all points' values are zero. PointWeightMap.h  

int32 Num()

 Return the number of values in this map. PointWeightMap.h  

void SetValue ( int32 Index,
float Value
)

 Set a value in the map checking first whether the index is within bounds. PointWeightMap.h  

Operators

Name Remarks Include Path Unreal Specifiers

const float & operator[] ( int32 Index
) const
